Pulled meat products are highly popular with consumers. In a meat production facility where the raw ingredients are relatively large pieces of meat, such as 38 ounces or larger, the amount of tearing/pulling necessary to obtain a desired piece size can be highly labor-intensive, resulting in relatively high costs to purchasers, such as restaurants and grocery stores.

The embodiments herein relate to a meat-tearing or meat-pulling machine that is configured to receive relatively large pieces of cooked meat, such as 24 ounces, 36 ounces, 48 ounces or larger, and automatically tear the meat pieces into smaller meat pieces which may be suitable in size for the intended purpose, or may be manually torn into even smaller meat pieces. The embodiments greatly reduce the amount of manual labor necessary to tear large quantities of relatively large pieces of meat into a suitable piece size. In some embodiments, the meat-tearing machine is adjustable to allow for a plurality of different piece sizes to be produced.

FIG. 1 is a first side view of a meat-tearing apparatus 10 according to one embodiment. The meat-tearing apparatus 10 includes a hopper 12 that includes at least one sidewall 14. In this embodiment, the hopper 12 has four sidewalls 14-1-14-4 (14-4 illustrated in FIG. 2), but in other embodiments, the hopper 12 may comprise a single circular or oval sidewall 14. The hopper 12 forms a first opening 16 configured to receive cooked meat articles (e.g., pieces of meat), and a second opening 18 configured to discharge torn meat articles. A rotatable spindle element 20 is positioned at least partially within the hopper 12 and in a downstream direction 22 with respect to the first opening 16. As will be discussed in greater detail below, the rotatable spindle element 20 includes a shaft 21 and a plurality of teeth coupled to the shaft.

In this example, the sidewall 14-1 includes an upper sidewall portion 14-1U and a lower sidewall potion 14-1L, the sidewall 14-2 includes an upper sidewall portion 14-2U and a lower sidewall potion 14-2L, and the sidewall 14-3 includes an upper sidewall portion 14-3U and a lower sidewall potion 14-3L. The upper sidewall portions 14-1U and 14-3U oppose one another and are sloped, are non-parallel with respect to one another, and taper in the downstream direction 22. In this embodiment, the lower sidewall portions 14-1L and 14-3L oppose one another, are non-sloped and are parallel with respect to one another; however, in other embodiments, the lower sidewall portions 14-1L and 14-3L may also be sloped to taper in the downstream direction 22.

The meat-tearing apparatus 10 includes a plurality of rods 24 that extend from sidewalls 14-1L and 14-3L. A motor (not illustrated in FIG. 1) is coupled to the rotatable spindle element 20 and is configured to rotate the rotatable spindle element 20 to cause at least some of the plurality of teeth to rotate and pass between two different rods 24 of the plurality of rods 24, thereby tearing a meat article caught between the teeth and the rods into smaller pieces.

In this embodiment the meat-tearing apparatus 10 is positioned above a conveyer belt 26 upon which torn meat articles 28 discharged from the second opening 18 land. If the sizes of the torn meat articles 28 are not sufficiently small, the torn meat articles 28 can be hand-torn into smaller pieces to achieve a desired size. While the meat-tearing apparatus 10 can be utilized with any type of meat, solely for purposes of illustration, the meat-tearing apparatus 10 is illustrated herein as being utilized in the processing of cooked chicken pieces.

FIG. 2 is a second side view of the meat-tearing apparatus 10. The sidewall 14-4 includes an upper sidewall portion 14-4U and a lower sidewall portion 1-4L. The upper sidewall portion 14-4U and the upper sidewall portion 14-2U are non-sloped and parallel with respect to one another. The lower sidewall portion 14-4L and the lower sidewall portion 14-2L are also parallel with respect to one another. In this example, the meat-tearing apparatus 10 includes 16 rods 24 (eight rods 24 illustrated in FIG. 2) that extend from two opposing lower sidewall portions 14-1L, 14-3L of the hopper 12 into an interior of the hopper 12. As will be discussed in greater detail below, the hopper 12 may include rod adjustment elements 30 that facilitate adjustment of the length of the rods 24 that are exposed to the interior of the hopper 12 to alter an average size of the torn meat articles 28.

The meat-tearing apparatus 10 includes a drive mechanism 32 that may include, for example, a motor, and in some embodiments a translation mechanism, to cause the rotatable spindle element 20 to rotate about a longitudinal axis 34 of the shaft 21.

FIG. 3 illustrates a view of an interior 36 of the hopper 12 of the meat-tearing apparatus 10. A plurality of spaced apart teeth 38, in this example fourteen teeth 38, are coupled to the shaft 21 of the rotatable spindle element 20 along a length of the shaft 21. The shaft 21 extends from the lower sidewall portion 14-2L to the lower sidewall portion 14-4L. The rods 24, which are also spaced apart from one another, extend from lower sidewall portions 14-1L, 14-3L into an interior 36 of the hopper 12. The rods 24 and teeth 38 are spaced such that the rods 24 and the teeth 38 are interlaced with one another. As the rotatable spindle element 20 rotates, each tooth 38 passes between two different rods 24 when the respective tooth 38 is rotating in a downward direction, and also passes between two different rods 24 when rotating in an upward direction. For example, a tooth 38-1 passes between two rods 24-1, 24-2 when rotating in the downward direction, and passes between two rods 24-3, 24-4 when rotating in the upward direction.

Each rod 24, 24-1-24-4 is slidably adjustable to alter a distance between an end of the respective rod 24, 24-1-24-4 and the shaft 21. The distance between the end of the rods 24, 24-1-24-4 and the shaft 21 affects a size of the torn meat articles produced by the meat-tearing apparatus 10. In particular, the larger the distance between the end of the rods 24, 24-1-24-4 and the shaft 21, the larger the size of the torn meat articles produced by the meat-tearing apparatus 10. In some embodiments, the teeth 38 are spaced a distance apart from one another, such as, by way of non-limiting example, a distance in a range between about 2 inches and about 4 inches. In some embodiments, the distance is about 3 inches, on center, as illustrated by a distance 42. Similarly, in some embodiments, the rods 24, 24-1-24-4 are spaced a distance apart from one another, such as, by way of non-limiting example, a distance in a range between about 2 inches and about 4 inches. In some embodiments, the distance is about 3 inches, on center, as illustrated by a distance 44. In some embodiments the shaft 21 has a diameter 46 between about 2 inches and about 4 inches. In some embodiments the shaft 21 has a diameter 46 of about 3 inches.

In this embodiment, the hopper 12 includes an interior wall 48 that divides the interior 36 of the hopper into two chambers 50, 52. The interior wall 48 has a bottom edge that is spaced a sufficient distance from the rotatable spindle element 20 to allow the plurality of teeth 38 to rotate about the longitudinal axis 34 of the shaft 21 and avoid contact with the bottom edge of the interior wall 48. In some embodiments, the bottom edge of the interior wall 48 is parallel to the longitudinal axis 34 and is spaced a distance from the longitudinal axis 34 such that when each tooth 38, during rotation of the rotatable spindle element 20, is at a closest distance to the bottom edge, the tooth 38 is in a range of about 0.5 inches to about 3 inches from the bottom edge. In this embodiment, the two chambers 50, 52 have equal volumes. In this embodiment, each chamber 50, 52 has a length 54 of about 25 inches, and a width 56 of about 10 inches.

FIG. 4 illustrates an enlarged view of several teeth 38, 38-2-38-4 coupled to the shaft 21 of the meat-tearing apparatus 10 according to one embodiment. The tooth 38-2 includes a support member 58 coupled to the shaft 21, and a meat-tearing element 60 coupled to the support member 58. In this example, the meat-tearing element 60 comprises a plate having a face 62 and edges 64, the edges 64 being planar and being 90 degrees or greater with respect to the face 62. In this embodiment, the meat-tearing element 60 has a length 66 of about 3 inches, a width 68 of about 1.5 inches, and a thickness 70 of about ⅛ inches. The teeth 38 may comprise any rigid material suitable for processing a cooked meat article, such as stainless steel or the like. In this embodiment, the teeth 38 are arranged in four rows along the shaft 21, each tooth 38 being positioned 90 degrees from an adjacent tooth along the shaft 21. For example, a tooth 38-3, in a first row of teeth 38, is positioned 90 degrees from the adjacent tooth 38-2 in a second row of teeth 38, which is positioned 90 degrees from an adjacent tooth 38-4 in a third row of teeth 38.

FIG. 5 illustrates an enlarged view of several teeth 38 and several rods 24, according to one embodiment. As the shaft 21 rotates, each tooth 38 passes between two rods 24, tearing any meat articles that are caught between the teeth 38 and the rods 24.

FIG. 6 illustrates a rod 24 according to one embodiment. In this embodiment, the rod 24 has a length 72 of about 5.5 inches in length and a diameter 74 of about 1 inch. The rod 24 has three openings 76. In this example, the openings 76 are blind holes and do not extend all the way through the rod 24, but in other embodiments, the openings 76 comprise through holes. The openings 76, as described in greater detail below, allow adjustment of the length of the rod 24 that is exposed to the interior 36 of the hopper 12. While only three openings 76 are illustrated, the rods 24 may comprise any number of openings 76.

FIG. 7 illustrates the rod adjustment elements 30 according to one embodiment. The rod adjustment elements 30 include a sleeve 78 fixed to an exterior of the hopper 12. The sleeve 78 forms a hollow cylinder that is in communication with an interior of the hopper 12. The sleeve 78 includes a rod-receiving opening 80 configured to receive a rod 24 to facilitate entry of at least a portion of the rod 24 into the interior 36 of the hopper 12. The sleeve 78 includes a rod-locking mechanism 82 configured to lock the rod 24 with respect to the sleeve 78 to inhibit movement of the rod 24. In this embodiment, the rod-locking mechanism 82 comprises a pin 84 that can be inserted into a pin guide 86 to engage an opening 76 in the rod 24 that is positioned in the sleeve 78 to thereby inhibit movement of the rod 24.

FIG. 8 illustrates a plurality of rods 24 locked via corresponding rod adjustment elements 30 to expose a desired length of the rods 24 to the interior 36 of the hopper 12 according to one embodiment.

FIG. 9 illustrates another view of the meat-tearing apparatus 10 according to one embodiment. The meat-tearing apparatus 10 includes a motor 88 that is configured to rotate the shaft 21. In this view, the rods 24 have been removed from the sleeves 78.

FIGS. 10A-10D illustrate the meat-tearing apparatus 10 at four different instances in time during operation according to one embodiment. Referring first to FIG. 10A, the rotatable spindle element 20 rotates the teeth 38 in a direction 90. In this embodiment the shaft 21 has a perimeter 92, and each rod 24 has a respective longitudinal axis 94, and lines that are collinear with the respective longitudinal axes 94 intersect the perimeter 92 of the shaft 21. In this embodiment, the interior wall 48 is in a plane that intersects the longitudinal axis 34 of the shaft 21. In this embodiment, a closest distance 96 between a tooth 38 and a bottom edge 98 of the interior wall 48 is in a range of about 0.5 inches to about 3 inches.

Referring now to FIG. 10B, as the rotatable spindle element 20 rotates, a plurality of meat articles 100-1-100-4 are introduced into the chamber 52. Note that meat articles may also be introduced into the chamber 50, and thus meat articles can be concurrently introduced into the hopper 12 from both sides of the hopper 12. The meat article 100-1 lands between at least one tooth 38 and the interior wall 48. Referring now to FIG. 10C, one or more teeth 38 urge the meat article 100-1 in a direction toward and past the interior wall 48, where some of the meat article 100-1 impacts the interior wall 48, and the meat article 100-1 is thereby torn by the teeth 38 and the interior wall 48 into a plurality of torn meat articles 102. Referring now to FIG. 10D, the teeth 38 urge the plurality of torn meat articles 102 against one or more rods 24, further tearing the plurality of torn meat articles 102 into a plurality of smaller meat articles 104. The smaller meat articles 104 exit the second opening 18 and, in some embodiments, drop to a conveyer belt. If the smaller meat articles 104 are not the desired size, individuals on both sides of the conveyer belt can manually further tear the smaller meat articles 104 into torn meat pieces of the desired size.
